To aZZ whom it may concern Be it known that we, JAMES J. LYNCH and HENRY PFLUGER, citizens of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Upsetting-Tools, of whichthe following is a specification. Y

Our invention relates to improvements in upsetting tools or apparatus designedpar'- ticularly for upsetting the ends of old axles, draw bars, or similar parts to allow remachining of the same.

To this end the invention consists in the features of construction, combination, and arrangement of parts hereinafter described and claimed.

In the accompanying drawings forming part of this specification,'Figure 1 is a top view of our improved device; Fig. 2 is a side elevation of the same; Fig. 3 is an axle sup porting saddle forming part of the device; Fig. 4 is a detail of an anchoring plate for reinforcing rods; Fig. 5 is a side elevation of a trip hammer shown in operative connection with our device; Figs. 6 and 7 are side and front views of an upsetting plate; Fig. 8 is a side view of another form of upsetting plate; Figs. 9 and 10 are top and side views of one end of the device adapted for upsetting draw bars; and Fig. 11 is a side view of the end of the device opposite to the end shown in Figs. 9 and 10 and adapted for upsetting draw-bars.

As shown in the drawingsv the tool consists of a metal frame 2 having at its ends abutments 3 and 4, respectively. To strengthen the frame, the abutments are connected by means of twin rods 5, bolted at their ends in plates 6, said plates being positioned in openings 7 in the abutment ends of the frame and being formed with ribs 8 overlapping the sides of the frame and thereby holding the rods from lateral movement.

9 represents a rest or saddle for the part being upset as the axle 10. The saddle consists of a U-shaped piece of metal, the arms 11 of which fit over the sides of the base member of the frame, whereby the axle notv only is supported above the frame but is also held from lateral movement. When the axle is in place as shown in Figs. 1 and 2 there is inserted into the frame at the inner side of the abutment 3 an upright plate or die 12 having on its inner face a rounded boss 13. Between the plate 12 and the inner downwardly inclined face 14 of Vthe Vabut- 'Y ment 3 ,is inserted a wedgell. vThe wedgeis then driven down by means of the hammer portion 16 of a suitable trip hammer B. The trip hammer B forming `n'o part of the novelty of our invention is not specifically shown or described, but may be of any usual construction. Y

The driving downward of the wedge will Y drive the die 12 against V'the end of the axle,

effectively spread the extreme end of the axle for forming a collar and the use of the Hat die 17 thereafter will Hatten the end of the spread axle.

In Figs. 9,10, and 11 we show our tool adapted for use in connection with a draw bar 19. lWhere, after long use, the eye 20 of the draw bar has become lengthened, the

draw bar is inserted in the upsetting tool toV partly close the eye. For that purpose we employ a plate or die 21`to take the place of the dies 12 and 17 said die 21 being curved on its inner side to t against the curved end of the draw bar. The die is driven against the draw bar by means of the wedge 12. we employ a removable abutment 24 which can be positioned inside the xed abutment, as shown in Fig. 11. The removable abutment preferably carries side plates 25 to extend downwardly against the sides of the base plate of the upsetting tool. Any space between the removable abutment and permanent abutment maybe filled as by shims or lling plates 26.

22 is a yoke adapted to surround the axle to hold the same in the saddles or rests '3, said yoke being secured in position by means of keys 23 passing through the lower ends of the yokes and underneath the base of the axle holding frame.

We claim:

1. An upsetting tool of the class described comprising a base plate, end abutments, a die movably positioned inside one of said abutments, and a wedge sl'idable between said die and the adjacent abutment.

As the draw bars are shorter than axles 2. An upsetting tool of the class described comprising a base plate, end abutments, u die movably positioned inside one of said abutments, a wedge slidable between said die and the adjacent abutment, and brace rods adjustably connecting said abutrnents.` v 3. An upsetting tool of the class described comprising a base, rests for the part vto be upset inovably supported upon said base,A

abutments carried by said' base, one ofsaid abutments having a downwardly inclined inner face, a die nio-vably positioned inside said inclined abutment face, and a wedge downwardly slidable between said die and inclined face.

4. An upsetting tool of the class described comprising a base, rests for the part to be VVVwardly slidable between said die and yinclinedV face, and a yoke removably supported bye-said fraine'in"l position to surround the` part to be upset.

In testimony kwhereof wefaiixv our signatures 'in presence oi two witnesses.
